Lower the protein shake, as scientists warn him

If you're the kind of man whose finishing program involves polishing a protein shake, listen well: a new study has concluded that drinking too much protein supplements would not help you live long and healthy lives.

In the study, published in the newspaper Metabolism of natureResearchers at the Charles Perkins Center at Sydney University say that while branched-chain amino acids help build muscle, drinking too much can shorten lifespan, lead to weight gain, temper temperament and disrupt the sleep.

The researchers came to this conclusion after testing the effect of different amounts of BCAA on the health and body composition of the mice.

The mice received either twice the normal amount of BCAA or the standard amount or half or a fifth during their lifetime. They found that mice fed twice the normal amount of BCAAs increased their food intake, resulting in obesity and reduced shelf life.

"BCAAs supplementation has resulted in high levels of BCAAs in the blood, which rival tryptophan for transport in the brain," said Stephen Simpson, academic director of the Charles Perkins Center.

"Tryptophan is the only precursor of the serotonin hormone, often referred to as the" chemical substance of happiness "for its beneficial effects on mood and its role in promoting sleep. But serotonin does more than that and that's where the problem lies, "he said.

"This then lowered serotonin levels in the brain, which was a powerful signal to increase appetite. The decrease in serotonin caused by excessive consumption of BCAA resulted in massive overfeeding in our mice, which became extremely obese and led a shorter life. "

Nevertheless, for units that did not want to give up their protein habit for now, the researchers had some tips. Rather than consuming protein drinks, researchers recommend varying your protein intake. BCAA's are found in protein-rich foods like red meat, dairy products, chicken, fish and eggs, each providing a variety of essential amino acids. Vegetarians can find BCAAs in bean, lentil, nut and soy protein.

"It's important to vary the protein sources to get a variety of essential amino acids as part of a healthy and balanced diet, rich in fiber, vitamins and minerals," said the nutritionist. in Public Health from the University of Sydney, Rosilene Ribeiro.
